Currently VMM is using unattend.xml for domain joins for VMs and Hyper-V hosts. This contains having unencrypted passwords stored as cleartext at some points of time during the deployment.

We would prefer using offline domain join instead - as it was done for nano server in the past.

Add VHD Set support in VMM. Support for shared VHDX and now VHD Set has been requested for years, yet VMM ignores this critical feature.

One of the greatest advancements of VHD Set over shared VHDX is the ability to migrate vhd set, yet VMM has no support for this.

Please add VHD Set management (create, attach, dettach, migrate ....) to VMM.

When deploying a VM from a template, I rename the boot disk the template is made from to "system.<fullvmname>.vhdx" because I do not want the disk created as "<vmtemplatename>.vhdx. If there was a way to setup a rule to do this, it would be nice.

Since Windows Server Container Support. It should be possible to create Containers and Hyper-V Containers with SCVMM. Also suggesting to integrate Kubernetes Management Board Integration into SCVMM since Kubernetes Support Windows Containers.

It would be great if the Operating System list was something the administrator could define, but in lieu of that, add FreeBSD and OpenBSD as additional OS options for VMs.

I find it frustrating when I'm moving a lot of resources around, to have to clear out the "missing" items from the library. Library should be just treated like file explorer essentially. When its gone, its gone. If people like a audit trail, the offer a "keep history for x days" then show as missing......for x days. That would be better.

When pushing a VMM 2016 UR4 agent to an infrastructure server. If the infrastructure server has an existing certificate bound to HTTPS, example RDSGateway and Network Controller. The agent installation will remove the existing certificate binding when setting up BITS.

The requirement for running sysprep when preparing VM Templates (with Windows) looks a bit confusing, because as soon as you start converting finalized VM, the status changes to 'Sysprepping...'.

If VMM could do sysprepping on it's own, I'd like to be able to skip doing this step in my Task Sequence, because one of the last steps I'm doing is applying some hardening GPOs, which in turn, cause sysprep to succeed only after a subsequent reboot (and automating one is quite a challenge as apparently MDT doesn't like something that's being touched by the hardening policies)

very annoying having to build a whole new profile just for testing a minor change, especially when there is a complex network setup.

Update the VM and Hosts Dashboards management pack that was released for VMM 2012 and SCOM 2012. This Management Pack can no longer be imported into a SCOM 2016/VMM 2016 monitoring scenario.
System Center 2012 R2 Management Pack for Virtual Machine Manager Host and Virtual Machine Dashboards
https://www.microsoft.com/en-us/download/details.aspx?id=43707&WT.mc_id=rss_alldownloads_all

Without this Management Pack the usability of SCOM for monitoring the Hyper-V Hosts and VMs is virtually non-existent

Currently (1801) we are unable to remove optical media from a running VM although it is supported and doable from the failover cluster manager.
Please fix that.

There are times when you need to give the virtual machine a trunk-port. This has to be done through Powershell: Set-VMNetworkAdapterVlan -Trunk -AllowedVlanIdList xxx -NativeVlanId yyy
I would like to add the option in the GUI settings of the network adapter of the virtual machine for easy of use.

As SET switches don't support LACP

By default an algorithm is in place to affinitize a vNIC to a Physical network adapter when they are in a team (LBFO or SET). This algorithm does not always do the things you want, If I have two storage NICs created on my vSwitch I would like them affinitized both on a different physical adapter.

Set-VMNetworkAdapterTeamMapping -VMNetworkAdapterName SMB_1 –ManagementOS –PhysicalNetAdapterName “SLOT 2”
Set-VMNetworkAdapterTeamMapping -VMNetworkAdapterName SMB_2 –ManagementOS –PhysicalNetAdapterName “SLOT 3”

An easy to use web based management option like App Controller should be provided for VMM 2016. Setting up Windows Azure Pack just in order to give internal customers e.g. developers a tool to manage their VMs seems oversized.

In some cases customers work on dedicated admin workstations a local VMM Console installed. In these scenarios it's important to keep the console up-to-date, if possible in the same version as the VMM Server. It would be great if the VMM Console notifies the user if he's using and older VMM Console version.

at least this should be displayed within the "about" dialog.

Currently the Create Logical Unit wizard offers two options:
thin provisioned and thick provisioned.
Please add 'Thin provisioned and deduplicated'
Or give each storage pool a default settings option, in which the new LUN defaults for that pool are saved (thin/thick, deduplication, compression, ...)

Hyper-V 2016 adds a new feature called Virtual Machine Multi-Queue that allows a since VM to have multiple VMQ queues assigned to it to increase throughput. However, this can only be enabled by going into Hyper-V itself and not through VMM. It should be added as a new checkbox to the "Offload Settings" section for Virtual Network Adapter Port Profiles.
